MOSA MS6720 3 Stereo Inputs / 4-Channel Outputs Audio Processor 3 Stereo Inputs and 4-Channel Outputs Volume, Balance, Fader and Selectable Input Gain FEATURES •Operation range : 2.7V~5V •3 stereo inputs with selectable input gain •4 independent speaker controls for fader and balance •Independent mute function •Volume control in 1.25 dB/step •I2C interface •Components less and good PSRR •Housed in SOP20, SSOP20 packages APPLICATIONS •Portable audio device •Car stereo audio •Hi-Fi audio system •Cross-reference: PT2313L-20 DESCRIPTION The MS6720 is a 3 stereo inputs/4-channel outputs digital control audio processor for the low voltage operation. Volume, balance (left/right), and fader (front/rear) processor are incorporated into a single chip. The MS6720 also has selectable input gain. All functions are programmable via the serial I2C bus. The default states of the chip as the power is on are: the volume is -78.75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage are 0dB. The stereo 4 is connected internally, but not available on pins.
